16V Lit-Ion Battery

[SIP_GUY]

The factory Li-ion battery is 15.5V. People still call it a 12v but its not. So, no, there isnt two different factory Li-Ion batteries for Model 3, there is only one Factory li-ion battery for model 3 and its the one you have.

I keep specifying "factory" because aftermarket Li-ion batteries are not relevant for this question / discussion.

Sorry NOT true my MY manufactured 4/22 in Fremont has a 12V same form as the 16V

If you have a lithium ion battery, stock, from tesla, its the same one as every other tesla model Y that has a lithium ion battery. There are not 2 types of factory lithium ion batteries.

Given another thread popped up, I should clarify people talking about "12V Li-ion" were not lying. When the first versions came out the label said "12V Li-ion". It was later when they relabeled it "16V Li-ion" as per OP in thread. This is why some people say they have a 12V Li-ion from Tesla given that is literally what the label says:

Tesla is using a new 12V Lithium-ion battery in the Model S Plaid

Among the many changes that Tesla implemented in the new Model S Plaid, a new, 12-volt lithium-ion battery is one of the most subtle yet significant improvements the company made to its flagship sedan. The new 12V li-ion battery replaces the conventional lead-acid battery that has been...

The lithium battery that debuted with the 2022 model year is 15.5V and replaces the old lead acid 12V battery that was in previous model years. There is/was no lithium 12V battery.

Thanks for your reply
It is confusing why in the hell would they put a 12V sticker on it???

I don't think Tesla low voltage Lithium batteries have ever been 12V.

It's non-Tesla, third-parties low voltage Lithium batteries that are 12V. These are for older cars with traditional rounded +/- terminals that you can easily access to (easily use a clamp on), not a big special big connector that you can't use a clamp on.

You're correct. Some of the earlier 16V Li batteries seem to be mislabeled as "12V". WeberAuto on YouTube shows an OEM mislabeled as "12V". It tested at 16V.

Does anyone know why Tesla has two Lit-Ion batteries?

they don't. some 16V batteries are mislabeled. this video explains it well:
